  NAME

    md - Converts a text file to an MHS routing table

  SYNOPSIS

    md filename

  DESCRIPTION

    The md command converts a text file prepared by the message handling
    system (MHS) system administrator to a routing table used by the message
    transfer agent (MTA) processor.

    The input file describes the topology of the network and defines the
    following:

    ⊕  All message transfer agents (MTAs) in the network.

    ⊕  The quality of service (QOS) associated with each MTA and with each
       RTS-to-RTS (Reliable Transfer Server) connection.  The QOS parameter
       list is optional.

    ⊕  The originator/recipient (O/R) name associated with each MTA in the
       network.

    ⊕  The connectivity of the MTAs.

    ⊕  The maximum number of alternate routes for each system.

    The md command determines the shortest routes between all MTAs, then
    generates fixed routing tables for specified systems.  A table must be
    generated for each MTA on the network that uses the Intergraph X.400 MHS.

    Refer to the message handling system (MHS) tutorial in the Intergraph
    ISO/OSI Administrator's Guide for details on building the source text
    file.

  EXAMPLE

    To convert a text file named mytable.rt to a routing table, enter:

    md mytable.rt


  DIAGNOSTICS

    Following are possible command error messages and corrective actions:

    Maximum number of alternate routes is 6
           A real system cannot have more than six alternate routes.

    Undefined name
           A subnetwork in the systems description is missing from the network
           description file.

    Maximum vertices exceeded
           The defined total of subnetworks and systems exceeds the capacity
           of a compiler table.  The VERTICES parameter must be increased.
           However, see the next message.

    No RAM for array xxxxxx
           The operating system could not allocate enough memory for the
           compiler to process the VERTICES parameter.  Either reduce the
           parameter, or expand the memory of the compile-time system.

    string space full
           Fewer names, or shorter names, must be used; the total character
           count is too great to process.

    address space full
           Fewer addresses (O/R Names), or shorter ones, must be used; the
           total digit count is too great to process.

  FILES

    /usr/lib/mhs/rt/md.tab
           ASCII file utilized for debugging.

    /usr/lib/mhs/rt/default.rt
           Default routing text file used with md command.

  EXIT VALUES

    The Calculating shortest paths. message appears when the compiler is run.
